Cassam (2023) argued in this journal that vice-charging -- the practice of charging others with epistemic vices such as gullibility and dogmatism -- can itself be epistemically vicious. He focused, in particular, on charges of gullibility and dogmatism directed at parents hesitant to allow their kids to be vaccinated with the MMR vaccine. In this paper, I build on and extend his case by discussing relevant work he did not address. This includes work by Navin (2016) on parental vaccine refusal, recent empirical work concerning the link between differing moral values and COVID-19 vaccine hesitancy, and recent empirical work on vaccine uptake and moral reproach. The work discussed here has important implications for public education efforts that aim to increase vaccine uptake.
